Moving VSE sequences between files
Q: Is there a way to copy the metastrip from one file and move to another?
Yes. You can Append a Scene from one blend file to another and copy&amp;paste its (meta)strips you want, between scenes of current blend file.

Blender 2.8x and newer - if I open a blend and go to File &gt; Append I can navigate to saved blend and choose existing Scene.A and Scene.B (from attached blend file here). From thouse appended scenes I can Copy ⎈ Ctrl+C any strip (image, text, color ... or metastrip) and Paste ⎈ Ctrl+V into another scene of the same blend file.


Note: Just to prevent confusion. When you are in VSE editor and press Add ⇧ Shift+A &gt; Scene this operator adds a strip with Camera view from 3Dview editor includede Compositor result as well (when used).
Like here I created Scene.C in a new blend, appended Scene.B, then copy-paste text strip to Scene.C and added &quot;Scene&quot; strip (that's 3Dview scene - default cube with Normal Matcap, plus Blur node in Node Compositor).
